Prometheus二进制部署
### 一、prometheus搭建
prometheus官网下载地址：[Download](https://prometheus.io/download/)
下载最新的包2022-11-23
```
wget https://github.com/prometheus/prometheus/releases/download/v2.40.3/prometheus-2.40.3.linux-amd64.tar.gz
```
创建prometheus目录
```
mkdir -p /opt/monitor
```
解压移动
```
tar -zxf prometheus-2.40.3.linux-amd64.tar.gz
mv prometheus-2.40.3.linux-amd64 /opt/monitor/prometheus
```
添加systemctl管理
vim /etc/systemd/system/prometheus.service
```
[Unit]
Description=prometheus
[Service]
ExecStart=/opt/monitor/prometheus/prometheus --config.file=/opt/monitor/prometheus/prometheus.yml
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
启动prometheus
```
systemctl daemon-reload
systemctl start prometheus.service
systemctl status prometheus.service
```
### granfana搭建
granfana官网下载地址：[Download](https://grafana.com/grafana/download)
#下载截止2022-10-23最新版本
```
wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.2.6.linux-amd64.tar.gz
```
```
tar -zxvf grafana-enterprise-9.2.6.linux-amd64.tar.gz
mkdir -p /opt/monitor
mv grafana-9.2.6 /opt/monitor/grafana
```
vim /etc/systemd/system/grafana.service
```
[Unit]
Description=grafana
[Service]
ExecStart=/opt/monitor/grafana/bin/grafana-server -homepath=/opt/monitor/grafana
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
```
systemctl daemon-reload
systemctl start grafana.service
systemctl status grafana.service
```
### node_exporter：用于监控Linux系统的指标采集器
prometheus采集器地址：[Exporters and integrations | Prometheus](https://prometheus.io/docs/instrumenting/exporters/)
```
wget https://github.com/prometheus/node_exporter/releases/download/v1.4.0/node_exporter-1.4.0.linux-amd64.tar.gz
```
```
tar -zxf node_exporter-1.4.0.linux-amd64.tar.gz
mv node_exporter-1.4.0.linux-amd64 /usr/local/node_exporter
```
vim /etc/systemd/system/node_exporter.service
```
[Unit]
Description=node_exporter
[Service]
ExecStart=/usr/local/node_exporter/node_exporter
#ExecStart=/usr/local/node_exporter/node_exporter --web.config=/usr/local/node_exporter/config.yml
ExecReload=/bin/kill -HUP $MAINPID
KillMode=process
Restart=on-failure
[Install]
WantedBy=multi-user.target
```
```
systemctl daemon-reload
systemctl start node_exporter.service
systemctl status node_exporter.service
```
配置prometheus
末尾添加配置，ip地址为安装node_exporter的地址
vim /opt/monitor/prometheus/prometheus.yml
```
- job_name: "node"
static_configs:
- targets: ["192.168.1.50:9100"]
```
访问prometheus的ip:9090查看
点击Status ----> Targets 查看
登陆granfana页面ip:3000
默认密码admin admin 初次登陆需要修改密码
点击左侧设置 ----> Data sources
添加监控模板
效果如图
